Product Overview

The MCP3911A0-E/ML is a 2-channel Analog Front End (AFE) containing two synchronous sampling delta-sigma analog-to-digital converters (ADC), two PGAs, phase delay compensation block, low-drift internal voltage reference, modulator output block, digital offset and gain errors calibration registers and high-speed 20MHz SPI compatible serial interface. The MCP3911 ADCs are fully configurable with features such as, 16/24-bit resolution, OSR from 32 to 4096, gain from 1x to 32x, independent shutdown and reset, dithering and auto-zeroing. The MCP3911 is capable of interfacing a large variety of voltage and current sensors including shunts, current transformers, Rogowski coils and Hall effect sensors.
  • 94.5dB SINAD, -106.5dBc Total harmonic distortion (THD) (up to 35th harmonic)
  • 111dB Spurious-free dynamic range (SFDR) for each channel
  • Programmable data rate up to 125ksps
  • Ultra low-power shutdown mode with <2µA
  • -122dB Crosstalk between the two channels
  • 7ppm/°C Low drift internal voltage reference
  • Differential voltage reference input pins
  • High gain PGA on each channel (up to 32V/V)
  • Phase delay compensation with 1µs time resolution
  • Separate modulator outputs for each channel
  • Oversampling ratio up to 4096
  • Individual 24-bit Digital offset and gain error correction for each channel
  • High-speed 20MHz SPI Interface with mode 0,0 and 1,1 compatibility
  • Continuous Read/Write modes for minimum communication
  • Low power consumption (8.9mW at 3.3V, 5.6mW at 3.3V in low-power mode, typical)
